Nebulae Challenge – Clouds Among the Stars

Nebulae are vast clouds of gas and dust in space. Some are stellar nurseries where gravity pulls material together to form new stars, while others are the glowing remains of dying stars.

Famous nebulae include the Orion Nebula, visible to the naked eye, the Eagle Nebula with its Pillars of Creation and the Crab Nebula, the remains of a supernova seen in 1054. Planetary nebulae like the Ring Nebula form when Sun-like stars shed their outer layers.

Telescopes reveal stunning colors as hydrogen, oxygen and other gases glow. The James Webb Space Telescope can see through dust, showing young stars hidden inside nebulae.
